You have to understand, Germany had the best military in the world in WW2, and should have won because:

1.) The Wehrmacht committed no atrocities
2.) The Tiger and Panther were the best tanks to have been built, before or since
3.) Not everyone was a nazi
4.) Stalin killed more people than Hitler
5.) The allies committed just as many war crimes, somehow
6.) Soviet soldiers raped some German women
7.) The Iron Cross
8.) If they had just done a few things slightly differently, they would have won
9.) Erwin Rommel
10.) Krupp Stahl
